SNOW-PLOW.

Specification of Letters Patent. 7 Patented Sept. 28, 1915.

Application filed June 28, 1915. Serial No. 38,568.

To all whom it may concern: I

Be it known that I, ANDREW RYAN, a'citizen of the United States,residing at Knob,

in the county of Shasta and State of California, have invented new and:useful Improvements in Snow-Flows, of which the following is aspecification.v

The object of the-present invention is to provide an improved snow plowbe operated in front of a locomotive engine to clear railroads of snow.In the accompanying drawing,.Figure 1 is a side view, showing myimproved snow low attached to a locomotive engine, the front portiononly of said .engme being shown; Fig. 2 is a plan view of the same; Fig.3 is a transverse vertical section on th line 3-3 of Fig.1...-

'- Referring to the drawing,l indicates a locomotive engine of animproved type. In ap lying my improv snow plow thereto I rst remove'thecow-catcher, which is ordinarily. securedto a transverse beam 2 securedby hangers 3 from the front end of said locomotive engine. I thenreplace it by:

ing the plow into two chambers 12 and forming a central downwardly andforwardly sloping slightly concave rid e 13 uniting the apexespf thebase and wal A damper 14 is placed in the smoke stack of the locomotiveen inc, and, when the snow plow is attache to said engine, the damper isclosed. A pipe 15 leads forwardly from a point below the damper and thenbranches into two pipes 16, each connected with one of the chambers 12of the plow above downwardly and forwardly sloping partitions 17. Bythis means the hot and waste gases from the smoke-stack of thelocomotive engine are discharged into said chambers, adjacent to theupper walls 18 thereof, thus conveying heat to said walls, so that theyare maintained continually hot. The snow in contact therewith is quicklymelted so that the snow encountered by the snow plow of the locomotiveis easily penetrated and thrown to the sides of the track. Part of thewaste gases pass out through pipes 20 which lead to the upper portion ofthe smoke stack above the damper.

Air is admitted into the plow by a pipe 21 having a funnel-shaped inletend in front of the locomotive, the partition 11 having holes in thelower portion to permit the waste gases to pass from one chamber to theother.

22 indicates an oil burner which may be usedinsteadof, or in additionto, the waste gzlises of the locomotive for heating the Should theweight of the snow bearing down uponthe snow plow be very considerable,said weight will cause a V-shaped rod .23 secured to'the base 7 tocontact with the railsand slide' thereon'as the snow plow is propelled bthe engine.

Side shie ds 24 are connected to the rear end of the-plow and extendover the sides of the locomotive and have their upper portions-25'curled over or'outwardly downward to protect the sides of thelocomotive.

26 is a man hole for entering the interior of the snow plow.

I claim:

1. In combination with a steam locomotive having a dam 'er in itssmoke-stack, a snow plow adapte 'to be attached to said locomotive a rodto which said base is secured and having a hooked portion adapted toengage a transverse beam in front of the locomotive to-which the cowcatcher is normally attached, a pipe leading from said smoke stack belowsaid damper into the in- -terior of said plow,- a pipe leading from thelower portion of said interior and dislOU said damper, and a rodconnected to the lower portion of the snow low and adapted to slide uponthe rails i the plow is depressed.

3. In combination with a steam locomotive having a damper in itssmoke-stack, a snow plow adapted to be attached to said locomotivecomprising a forwardly pointed base, an upwardly pointed rear wall, acentral downwardly and forwardly extending ridge uniting the points ofsaid base and rear wall, means for securing the plow to the locomotive,a forwardly and downwardly cxtendin partition from said rear wall, apipe leading from said smoke stack below said damper, branch pipesleadin from said pi Jo and discharging into the interior of said plowabove said partition, pipes lead-- ing from the lower portion of saidinterior and discharging into the smoke-stack above said damper, and apipe leading from the interior of the low and dischaging upwardly infront 0 the locomotive.

4. In combination with a steam locomotive having a damper in itssmoke-stack, a snow plow adapted to be attached to said locomotive comrising a forwardly pointed base, an upwar ly pointed rear wall, a central downwardly and forwardly extendin ridge uniting the points of saidbase and rear wall, means for securing the plow to the locomotive, aforwardly and downwardly extendin partition from said rear Wall, a pipelea ing from said smoke stack below said damper, branch pipes leadingfrom said ipe and dischaging into the interior of said plow above saidpartition, pipes leading from the lower portion of said intcrior anddischarging into the smoke-stack above said damper, and an oil burnerfor heating the interior of said plow.

5.111 combination with a steam locomotive having a damper in itssmoke-stack, a snow plow adapted to be attached to said locomotive comrising a forwardly pointed base, an upwar ly pointed rear wall, acentral downwardl and forwardly extendin ridge uniting t e points ofsaid base an rear wall, means for securing the plow to the locomotive, aforwardl and down wardly extending partition rom said rear wall, a pipeleading from said smoke stack below said damper, branch pipes leadingfrom said pipe and discharging into the interior of said plow above saidpartition, pipes leading from the lower portion of sai interior anddischarging into the smoke-stack above said damper, and a longitudinalpartition centrally dividing the interior of the locomotive intochambers and having holes therethrough through which the chamberscommunicate with each other.

6. In combination with a steam locomotive having a damper in itssmoke-stack, a snow plow adapted to be attached to said locomotivecomprising a forwardly pointed base, an upwardly pointed rear wall, acentral downwardly and forwardly extending ridge uniting the points ofsaid base and rear wall, means for securing the plow to the locomotive,a forwardly and downwardly extending partition from said rear wall, apipe leading from said smoke stack below said damper, branch pipesleading from said pipe and discharging into the interior of said plowabove said partition, pipes leading from the lower portion of saidinterior and discharging into the smoke-stack above said damper, an oilburner for heating the interior of said plow, a pipe leading from theinterior of the plow and discharging upwardly in front of thelocomotive, a rod connected to the lower portion of said base andadapted to slide upon the rails if the the plow is depressed, alongitudinal parti tion centrally dividing the interior of thelocomotive into chambers having holes there/through through which thechambers communicate with each other.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
